Fire Protection / Prevention Program
-
a.
Administrative Controls The inspector reviewed the following licensee administrative procedures:
AP 0216 revision 1, Plant Housekeeping Program;
--
--
AP 5005 revision 5, Standard Welding and Inspection Procedure.
The inspector verified that the licensee has developed administrative controls which include:
(1) Requirement for periodic inspection for, accumulation of combusti-bles.
(2) Control over the storage of flammable materials.
(3) Prohibition on smoking in safety related areas except where
" smoking permitted" areas have been specifically designated.
(4) Special authorization for activities involving welding and other open flame operations.
Administrative procedure AP 5005 requires t
I that the supervisor responsible for the cutting or welding operation evaluate the combustible loading in the proximity of the work area prior to approving the operations.
However, the procedure
!
does not specify the radius of area from the point of operations l
that should be examined nor does the procedure address the handling and protection of combustible materials within a specified radius of the work area.
During a walk-through inspection of the Turbine Generator Building, operating floor elevation, the inspector noted a welding operation in progress, within 10 feet of a wood working area, where 20-30 sheets of plywood were being cut, allowing an accumulation of sawdust on the fluor.

j The inspector reviewed Amendment No. 56 to Facility Operating i
License No. DPR-3.
Licensee submittal dated May 10,.1978 commits j
the licensee to conformance with guidelines of Attachment G of the NRC document titled, " Nuclear Plant Fire Protection, Functional
Responsibilities, Administrative Controls, and Quality Assurance."
Licensee's procedure AP-5005 did not incorporate the following NRC guidelines adopted from the National Fire Protection Association Code SIB:
8efore issuing the permit, the responsible foreman or super-
--
visor should physically survey the area where the work is to
,
be performed and establish that the following precautions
have been accomplished:
,
l (1) All movable combustible material below and within a 35 foot radius of the cutting, welding, grinding, or open flame work has been recoved.
(See NFPA 518)
(2) All immovable combustible material below and within a i
35 foot radius has been thoroughly protected by asbestos curtains, metal guards, or flameproof covers, and fire extinguishers, hose, or other firefighting equipment
)
are provided at the work site.
(See NFPA 51B)
i i
The licensee's failure to incorporate the above guidelines into
implementing instructions / procedures is considered to be a devia-tion from the licensee's commitment in Amendment No 56 (29/80-19-01).
The inspector noted that administrative procedures for the control of combustible and flammable materials have not been revised to
"
reflect the requirements of 10 CFR 50 Appendix R.
The licensee stated that the applicable procedures will be updated in accordance with the schedule outlined in 10 CFR 50.48, Fire Protection, paragraph C.
3.
Fire Brigade Training The inspector noted the licensee procedure AP-0503, Fire Protection Training, is under review..The procedure will be completed in acccedance with the schedule outlined in 10 CFR 50.48.
l No items of noncompliance were identified.
4.
Facility Tour i
The inspector exam'ned fire protection water systems, including fire pumps, fire water piping a.sd distribution systems, yard fire protection equipment l

including indi;ator valves, hydrants and contents of hose houses.
The inspector toured all accessible vital and nonvital plant areas and examined fire detection and alarm systems, automatic and manual fixed suppression systes ~ interior hose stations, fire barrier penetration seals, fire doors, and fire dampers.
,
The inspector exanined the control room, switchgear room and the turbine building which are identified as critical fire areas in TI2515/19.
~
The inspector noted that there are two rows of windows along the north wall of the turbine building at approximate elevations 1056 ft. and 1065 ft. The roof of the office building, located in the northwest area of the turbine building is within 10 ft. of the lower row of windows.
The combustibility of the office building roof, insulated metal deck type, could not be deter-mined during the inspection.
The inspector determined, however, that the interior suspended ceiling is of combustible fiberboard, attached to a wood lath.
The interior fire loading of the building is above the average for this type of occupancy, 15 -20 lbs/ft.sq. due to overloading of office equipment and materials.
The available fire protection for the office building consists of portable extinguishers, hose station and yard hydrants.
The inspector could not find evidence that the exposure of the office building to the turbine building structure and its contents and thus exposure j
to equipment required for safe reactor shutdown has been considered either by the licensee or the NRC review team.
This item is considered unresolved pending NRC review of:
a.
determination of the combustibility of the office building roof construc-tion, b.
determination of impact of an office building fire on equipment and structures required for safe shutdown.
(29/80-19-2)
5.
Fire Protection Modi:ications Required by Amendment No. 56 to OPR-3 By review and examination of records, including specifications, drawings, anJ associated quality assurance documents, and by examination of installed
,
l fire protection equipment throughout the plant, the inspector verified the licensee's implementation of scheduled modifications identified in Amendment
'
No. 56 to OPR-3.
The inspector verified that the following modifications have been completed l
l in accordance with Section 3 of the Fire Protection Safety Evaluation Report, attached to Amendment No. 56.
